![]() For instance, you may live in a Zone 5b area, but be able to grow a few select plants rated for Zone 6a if they’re grown in a warm, sheltered area.Ī hardiness zone map also doesn’t take into account environmental factors that vary throughout time. The hardiness zone map may also fail to account for microclimates (small areas where external factors have affected the climate). The limitations of a hardiness zone mapīecause most plant hardiness maps cover large areas of land, they cannot provide great detail for the boundary areas between zones. For this reason, it’s important to understand which plants are compatible with the specific hardiness zone in your area as this will help ensure success when planting. Though the map can give you a general idea of how to find your growing zone, it’s usually not detailed enough to account for microclimates and variations near plant hardiness zone boundaries. Make sure to note whether your garden lies within a defined plant hardiness zone, or if it’s close to a border between two different zones. To find out which plants will work best in your region, you need to check the map for your area and zoom into your local area. ![]() Each region has its own climate and temperature range so the plants that thrive in that area must be taken into consideration. Knowing your hardiness zone is an important factor when it comes to gardening, especially when growing flowers or vegetables. These maps will give you a general idea of your plant hardiness zones: The easiest way to estimate your growing zone is by referencing a Plant Hardiness Map. ![]() How to find your growing zones using plant hardiness maps? For example, if a given plant will survive in temperatures down to −28.9 ☌ (−20 ☏), it would be “hardy to Zone 5a”. When describing the lowest temperatures at which a plant will survive, gardeners will state the plant is hardy to a given zone. Zones can each also be divided into two sub zones, a & b. The categories in the system provide a numerical rating for the climate in a given area, based on the coldest winter temperatures in the area. The coldest zones on the scale are given the lowest numbers, with the zone numbers becoming higher as winter minimum temperatures increase. ![]() Learning how to find your growing zone will help you get in the mindset for gardening in your local climate.Īlthough there are many different systems around the world, the most popular classification system is the USDA’s system of Plant Hardiness Zones. Finding your category, known as your Plant Hardiness Zone, is a crucial early step in garden planning (even before selecting your crops). The climate categories they’ve created will help you learn what plants do well in your area. These hardy plants provide a range of benefits such as lowering maintenance costs since they don’t need to be planted annually! How to find your growing zones: Plant hardiness zones?įortunately, in most areas of the world, federal scientists have categorized geographical areas by climate. It can be so frustrating when you’ve spent time and money on a plant, only to have it die from external environmental factors.įor more than two years, often surviving through the winter months and returning each year in the spring. They simply aren’t adapted to the local environment. If you’re not aware of your local growing zone before you install your garden, any plants that aren’t matched to your unique climate may not survive. Due to this range in tolerances, knowing your local climate growing zone is a key factor in growing a successful garden. This is especially true for their temperature requirements. Plants vary widely in their tolerance of growing conditions. Have you ever gone out to your perennial gardens in the spring and discovered that some of your favourite plants haven’t made it through the winter? Or have you planted out some baby vegetable plants, just to discover one morning that they’ve been killed by frost? ![]() Growing zones Why knowing your growing zones important? ![]()
